Abstract

There is provided a system and method for manufacturing continuous strand fiberglass of progressive density with varying skins. Glass media is melted into molten glass within a temperature controlled melter, the molten glass exits the melter through orifices of a bushing plate, which is oriented 6 degrees relative to the axis of a rotating drum. A rotating drum receives the molten glass exiting the bushing plate, and resin and water are applied. The fiberglass media is fed through rollers before it enters a curing oven.

Claims (53)

1. A method of manufacturing fiberglass media comprising:

providing glass into a melter and through a bushing plate to produce continuous glass filament strands;

repeatedly traversing the melter above a rotating drum in a first direction along a substantial length of the rotating drum and an opposite second direction along the substantial length of the rotating drum;

depositing the continuous glass filament strands onto the rotating drum;

spraying resin onto the continuous glass filament strands on the rotating drum to form a fiberglass mat;

removing the fiberglass mat from the rotating drum;

providing the fiberglass mat through a roller apparatus comprising an upper roller and a lower roller;

applying a liquid consisting of water to the fiberglass mat; and

immediately after applying the liquid to the fiberglass mat, curing the fiberglass mat in a curing oven.

2. The method of claim 1 , comprising: orienting the bushing plate at a 6-degree angle relative to the first direction.

3. The method of claim 1 , comprising: cooling, via a cooling loop assembly, the continuous glass filament strands.

4. The method of claim 1 , comprising: spraying the resin onto a swath of the continuous glass filament strands deposited onto the rotating drum.

5. The method of claim 4 , comprising: spraying the resin in a width of between 4 inches and the width of the swath.

6. The method of claim 1 , comprising: spraying water onto a swath of the continuous glass filament strands deposited onto the rotating drum.

7. The method of claim 6 , comprising:

spraying the resin in a width of between 4 inches and the width of the swath;

spraying the water in a width of between 4 inches and the width of the swath.

8. The method of claim 1 , wherein the roller apparatus comprises bowed rollers.

9. The method of claim 1 , comprising: expanding the fiberglass mat before curing the fiberglass mat in the curing oven.

10. The method of claim 1 , comprising: providing the fiberglass mat onto a let-off table assembly.

11. The method of claim 10 , comprising:

applying heat to a first side of the fiberglass mat via a first heat source; and

applying heat to a second side of the fiberglass mat via a second heat source.

12. The method of claim 1 , comprising:

curing the fiberglass mat in a first chamber of the curing oven at a first temperature; and

curing the fiberglass mat in a second chamber of the curing oven at a second temperature, wherein the first temperature and the second temperature are not equal.

13. The method of claim 12 , comprising:

setting a height between an upper conveyor chain and a lower conveyor chain within the curing oven; and

providing the fiberglass mat between the upper conveyor chain and the lower conveyor chain.

14. The method of claim 13 , comprising: moving the upper conveyor chain at a different speed than the lower conveyor chain.

15. The method of claim 1 , comprising: removing the fiberglass mat from the curing oven and providing the fiberglass mat to accumulator rollers.

16. The method of claim 1 , comprising: weighing the fiberglass mat after removing the fiberglass mat from the rotating drum.

17. The method of claim 1 , comprising: controlling the temperature of the resin to within 10% of 70 degrees Fahrenheit.

18. A method of manufacturing fiberglass media comprising:

providing glass into a melter and through a bushing plate to produce continuous glass filament strands;

repeatedly traversing the melter above a rotating drum in a first direction along a substantial length of the rotating drum and an opposite second direction along the substantial length of the rotating drum;

cooling, via a cooling loop assembly, the continuous glass filament strands;

depositing the continuous glass filament strands onto the rotating drum;

spraying resin onto the continuous glass filament strands on the rotating drum to form a fiberglass mat;

removing the fiberglass mat from the rotating drum;

providing the fiberglass mat onto a let-off table assembly;

applying heat to a first side of the fiberglass mat via a first heat source;

applying heat to a second side of the fiberglass mat via a second heat source;

providing the fiberglass mat through a roller apparatus comprising an upper roller and a lower roller;

applying a liquid consisting of water to the fiberglass mat; and

immediately after applying the liquid to the fiberglass mat, curing the fiberglass mat in a curing oven.

19. The method of claim 18 , comprising:

curing the fiberglass mat in a first chamber of the curing oven at a first temperature; and

curing the fiberglass mat in a second chamber of the curing oven at a second temperature, wherein the first temperature and the second temperature are not equal.

20. The method of claim 18 , comprising:

setting a height between an upper conveyor chain and a lower conveyor chain within the curing oven; and

providing the fiberglass mat between the upper conveyor chain and the lower conveyor chain; and

moving the upper conveyor chain at a different speed than the lower conveyor chain.
